Via the Beeb:
Their American Journal of Clinical Nutrition study found that differences in body mass index and waist size were 77% governed by genes.
It strikes me that a more accurate interpretation is that 77% of obesity can be explained by genetic incompatibility with a modern western diet. Genetics dictates the potential for obesity. Everything else is environmental. Send those people off to the savanna with a sharp stick then get back to me.
It’s not a genetic disease like Tay-Sachs, where the mere presence of the genes equals the disease.

If this were not the case, the growing epidemic of obesity would imply that obese people are reproducing more, and are hence “genetically fitter,” than those of normal weight. That may be so but seems unlikely. It also means they are poping out babies like crazy over the past 20 years.
Well if it is true, I would like to report that over the Chinese New Year, I’ve mutated slightly and, due to my genetic make-up, I am larger by 1 pound
